The traditional culture methods for testing bacterial susceptibility to antibiotics are expensive and require 10¨C14 days. Since resistance to clarithromycin, fluoroquinolone, and tetracycline seems to be exclusively caused by specific mutations in a small region of the responsible gene, molecular methods offer an attractive alternative to the above-mentioned techniques. The technique of polymerase chain reaction (PCR) is an accurate and rapid method for the detection of mutations that confer antibiotic resistance. This review highlights the mechanisms of antibiotic resistance in H. pylori and the molecular methods for antibiotic susceptibility testing. %K Helicobacter pylori %K 23S rRNA %K gyrA %K PBP1 %K 16S rRNA %U http://www.frontiersin.org/Journal/10.3389/fmolb.2014.00019/abstract
